1

Part of body that extends from shoulder to the elbow

Arm

2

The two groups of muscles that cause movement at the elbow joint

Anterior Flexors
Posterior Extensors

3

Name the three anterior arm muscles

Biceps Brachii (long and short head)
Brachialis
Brachioradialis

4

Anterior muscle of the arm that has two bellys, long and short, and two different origins with a common insertion

Biceps Brachii

5

Which muscle of the biceps brachii is lateral?

Long head

6

What are the actions of the biceps brachii?

Flexes forearm
Primary supinator against resistance like tightening a screw

7

Biceps brachii that is medial and has a tendon attached to the corocoid process of the scapula that is often fused with the corachobrachialis

Short head

8

Muscle of biceps brachii that has a rounded chord like tendon that crosses the shoulder joint within the capsule of the shoulder

Held in place by the transverse humeral ligament

Long head of the bicep

9

The distal tendon of the biceps attaches to what structure?

What does it become after it continues after that point?

The radial tuberosity

It continues on to become the bicipital aponeurosis

10

A fibrous sheet or expanded tendon that serves as a muscle attachment along the medial aspect of the proximal part of the forearm

Bicipital aponeurosis

11

An area on the anterior surface of the elbow joint that is protected by the bicipital aponeurosis (veins lie superior to it for veinipuncture)

Cubital fossa

12

Where the long head of the bicep originates

Scapula at supraglenoid tubercle

13

When this tendon is torn, it results in a muscle bulge on the anterior of the arm known as the popeye deformity

Long head of the bicep

14

Nerve that innervates both of the muscles of the biceps brachii

musculocutaneous nerve from the

15

Biceps brachii are involved in which two types of movement?

Flexion and supination

16

The long head of the bicep has the ability to do what to the shoulder because it crosses the shoulder joint?

Flex the shoulder

17

Flattened muscle which lies deep to the biceps brachii

Brachialis

18

Where is the origin of the brachialis?

Insertion of the Deltoid (Deltoid tuberosity)

19

The brachialis is primarily responsible for what movement, particularly during slow movements?

Does it for both supinated and pronated positions unlike the biceps brachii.

Maintaining flexion of the forearm

20

Muscle that ALWAYS contracts during flexion of the elbow joint

Brachialis

21

What is the origin of the brachialis?

Coracoid process of the ulna

22

What nerve innervates the brachialis?

Musculocutaneous nerve

23

Arm muscle which may be considered part of the posterior forearm muscles that flexes the forearm, especially during quick movement

Brachioradialis

24

Does the brachioradialis cross the wrist joint? Can it cause wrist movement?

No and No

25

This muscle is active in rapid movements (flexion) of the forearm

Brachioradialis

26

The brachioradialis inserts where?

The styloid process of the radius

27

What is the origin of the brachioradialis?

Lateral supercondyle ridge.

28

What innervates the brachioradialis?

The radial nerve

29

The muscle that the musculocutaneous nerve goes through

Coracobrachialis

30

Nerve that hooks around the posterior aspect of the humerus towards the forearm

Radial nerve
